FLAT SHOE-UPPER MEMBER.

Specification of Letters Patent.

PatentedFeb. 25, 1919.

Application filed October 20, 1917. Serial No. 197,612.

To all whom 2'6 may concern:

Be it known that I, WILLIAM F.YLAUTEN SCHLAGER, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Flat Shoe-Upper Member, of which the following specification is a full disclosure.

My invention relates to a flat shoe upper member, or the like, such as a shoe lining and vamp held together for unitary han dling, as in lasting, still having slight rela tive movement.

One of the objects of the invention is to eliminate the spot cementing, or pasting commonly employed, and another object is to provide a temporary attachment device, which will adequately hold the vamp and lining together for handling, and which will yet permit of relative adjustability and movement of the vamp and lining, enabling an easier and more efficient pulling over of the shoe parts upon the last.

The features of the invention will} be more fully set forth in the description of the accompanying drawing, forming a part of this specification, wherein Figure 1 is a plan view of the vamp with the lining laid over in position, the dotted lines indicating the preferred insert positions.

Fig. 2 is an enlarged section on line 22, Fig. 1, showing the relative position of the parts after the insert.

Fig. 3 shows the parts compressed.

Fig. 4 is a sectional view, illustrating the function of the insert in providing relative adj ustability of the vamp and lining.

Fig. 5 shows a modification of the transversely flexible insert.

The following is an illustration of one method which can be employed in forming the article constituting my invention.

The vamp 1 being laid flat on the bench, the lining 2 is laid thereon in correct registry. The insert 3, shown, is preferably a hollow tape or strip of any desirable material, such as paper or cloth, having adhesive exterior and non-adhesive interior surfaces. The strip or insert may be simply folded upon itself, though I prefer the hollow tape form, shown in Fig. 2. The outer faces of the insert are adhesively secured respectively to the inner surfaces of the vamp-and lining, preferably, though not necessarily, after the lining is properly laid upon the vamp. The preferred position is indicated 1n Fig. 1, there being an insert running longitudinally of the vamp wings, upon oppos1te sides of the throat. The vamp and linlng are held in unison, slightly separated, as

shown in Fig. 2, and preferably the oper-- ator impacts or stamps the parts to bring them together, as indicated in Fig. 8.

When the preferred form of hollow insert, shown, is employed, the adhesive coating does not extend clear across the strip, but only a medial, longitudinal portion of the strip need be moistened, providing the flexible folds 7 The insert may be variously formed or treated, to provide this element of fiexibility of a vamp and lining adhesively secured to the insert.

The inner or meeting surfaces of the insert being non-adhesive, will permit of slight relative movements in directions transverse of the insert, the hollow insert flexing transversely to permit of this shifting or relative ad ustment, as indicated in Fig. 4. The parts are now temporarily, but not fixedly held together, so that they can be handled as a unit, as for sewing on the tip and shoe upper, and then being put to the pulling-over or lasting machine.

In pulling over or around the last, the vamp and lining, of course, have different radii of curvature, and the securance of this hollow type of insert enables the vamp and lining to be unitarily manipulated in the pulling-over operation and still provides for relative movement transversely of the insert, or compensation for the accommodation to the different pulling-over strains and positions and degrees of last curvature.

The position of the insert may vary with different Vamps, lasts and pulling-over or lasting processes, but, in general, the inserts are positioned between the medial portions of the vamp and lining, the strip length being placed so that its transverse line will correspond with the direction in which compensatory relative movements of the vamp and lining will be available in relation to the curves of the last to which both vamp and lining must conform.

Better results are obtained by using two inserts, as shown, or two folded tapes, as shown in modification, Fig. 5, wherein the two folded tapes 5 are employed, with their folded edges extending toward the outer edges of the vamp and their double edges extending toward one another, or in the general direction of the throat.

My invention is not limited to thenumber of inserts, or tothe precise structure, which can be variously modified, but the insert function is to providea strip flexible after adhesive application to provide relative adjustability of vamp and lining in directions coordinating with and compensating for the various pulling strains and curvatures incident to lasting operations.

Another advantage is that if the wrong vamp and lining have been assembled or improperly secured, they can be separated without danger of cutting or tearing the materials by simply slitting the insert.

The invention is not limited exclusively to vamp work, as it may be usefully employed in relation to the attachment of eyelet-stays, or other work where the characteristics of this invention may be advantageous.

Copies of this patent may be obtained for Having described my invention, I claim:

1. A flat shoe vamp and lining, and a flexible inserthaving surfaces adhesively secured between medial portions of the vamp and lining enabling a unitary manipulation and relative movement in lasting.

2. A flat shoe vamp and lining in approximate registry, and a folded insert having outer surfaces adhesively secured respectively to the inner surfaces of the vamp and lining respectively and having nonadhesive inner surfaces rendering the insert flexible, the insert being positioned to enable unitary manipulation of the vamp and lining, but rendering them relatively adjustable for conformation to last curves and pulling-over strains.

In witness whereof, I hereunto subscribe my name, as attested by the two subscribing witnesses;
